Locating and removing PIM interfering with a macro cell site can be a magnitude of difficulty greater than conducting the same exercise on a rooftop or similar microcell. In this post, we will...

Given the multitude of possible PIM causes on roofs, implementing the proper testing process using the appropriate test kit is essential.
